irrKlang
Neulengbach, Austria
What it is
irrKlang is a cross-platform sound engine and audio library for developers building 2D or 3D audio into projects using C++ or .NET languages. It plays WAV, OGG, MP3, FLAC, MOD, IT, S3M, and XM files, with both buffered and streamed playback. Spatial audio features include 3D sound emulation for low-end hardware and linear or logarithmic rolloff; available effects include echo, reverb, chorus, and distortion. The library can be used from C++, C#, VisualBasic.NET, and Delphi.NET. Plugins can add playback formats, and developers can supply their own file-format readers and decoders. irrKlang does not depend on Irrlicht, so projects can use it without that engine. It runs on Windows, Linux, and macOS. Non-commercial products can use it for free; commercial products require a Pro license. Listed one-time license options include €65 for hobbyists, €290 for indie use, €490 for one commercial product, and €2,950 for unlimited commercial products. Linux use requires ALSA, with matching 64-bit versions on 64-bit systems. Downloads are available only to existing licensees.
